simplify ((5a^2+8ab-21b^2))/((a+3b))

simplify

\frac{( 5 a ^{2} + 8 ab - 21 b ^{2} )}{( a + 3 b )}

5 a - 7 b

Solution steps

\frac{5 a ^{2} + 8 ab - 21 b ^{2}}{a + 3 b}

Factor

5 a^{2} + 8 ab - 21 b^{2} : (5 a - 7 b) (a + 3 b)

= \frac{( 5 a - 7 b ) ( a + 3 b )}{a + 3 b}

Cancel the common factor:

a + 3 b

= 5 a - 7 b

(- 10)^{0}

\frac{6}{x ^{2} - 4} + \frac{x}{x + 2}

4^{x} + 4^{x}

(a - x)^{4}

\frac{6 x}{24 x ^{2} - 216 x}
